A flow is a container of patches. Think of a flow as an app.
By selecting the Create tab at the bottom, you can see your flows.
By tapping the plus button at the top right corner, you can create a new empty flow.
By tapping the play button on a flow, you make it the currently active flow that you will be editing.
To change the name of a flow, delete it or add an image, tap the circle on the top right of a flow view.
